This ambiguous poem is a dialectical analysis of the tragic irony in the poet's fate as he is caught between the allurements of extreme idealism and his awareness that the very nature of man and the world precludes the achievement of his highest purpose. Alastor represents a transient but necessary phase in Shelley's evolution. He was hence-forth to return with unrelenting determination to his dual poetic task of defining the romantic ideal of universal harmony and of striving to bring about the reign of love and freedom in human society. The first fruits of this ripening were the Hymn to Intellectual Beauty and Mont Blanc, which were planned in 1816, during a stay in Geneva. Both poems constitute an impressive statement of Shelley's fundamental belief in an everlasting, benevolent "Spirit," the hidden source of splendor and harmony in nature and of moral activity in man. The Revolt of Islam

The winter of 1816-1817 was a period of great emotional disturbance for Shelley. Harriet died, presumably by suicide, in December, and the courts refused to grant Shelley the custody of the two children she had borne him. In addition, he was beginning to worry about his health. However, there were encouragements as well. Partly thanks to Leigh Hunt (to whom he gave financial help with his customary generosity), Shelley was gaining some recognition as an original and powerful poet. During the spring and summer of 1817, Shelley composed his most ambitious poem to date, The Revolt of Islam. In this work the crude allegorical didacticism of Queen Mab gave way to genuine, although at times still turgid, symbolism. The theme of love between man and woman was adroitly woven into the wider pattern of mankind's love-inspired struggle for brotherhood. Like the French Revolution, the failure of which had preoccupied Shelley for a long time, The Revolt of Islam ends in disaster. But the poet had now come to a mature insight, absent from Alastor, into the complex interplay of good and evil. Man's recognition of his boundaries is the first step to wisdom and inner liberty; martyrdom does not put an end to hope, for it is a victory of the spirit and a vital source of inspiration. The Revolt of Islam illustrates a discovery that often signaled the romantic poet's accession to wisdom and that John Keats described, in April 1819, as the recognition of "how necessary a World of Pains and troubles is to school an Intelligence and make it a Soul."

Exile and Prometheus Unbound

In March 1818 the Shelleys (still accompanied by Claire Clairmont) left England, never to return. The bulk of the poet's output was produced in Italy in the course of the last four years of his short life.
